Abstract
A dynamic fluid sealing system for a fuel injection valve employs sealing-fluid to separate a gaseous fuel and a second fluid in the fuel injection valve, thereby preventing leakage of the gaseous fuel into the second fluid. A pressure-balancing system, which includes a pressure-balancing device, reduces the pressure differential between the sealing-fluid and the gaseous fuel used in the injection valve. At the same time, the pressure balancing system dynamically balances the sealing-fluid pressure such that the sealing-fluid pressure is equal to or slightly greater than the pressure of the gaseous fuel within the injection valve. The pressure differential between the gaseous fuel and the sealing-fluid may be maintained throughout the operating range of engine speeds, engine loads, and fuel cut-off conditions so as to prevent leakage of compressible gaseous fuel into the second fluid. The reduced pressure differential between the gaseous fuel and the sealing-fluid also reduces leakage of sealing-fluid into the gaseous fuel.
